Question 2 (3 points)
Fill in the blank of the following sentence to make it true:

An adaptation of plants growing in the biome is they have deep roots to help them get moisture when it's dry, as drought is common in this biome. Fires are also common here, so the plants' deep roots also allow them to regrow if there is a fire.

a
Tropical Rainforest
b
Tundra
c
Desert
d
Grassland
Question 3 (3 points)
Desert biomes are arid, or dry, environments that receive less than 10 inches of rain each year. Some deserts can be very hot, while other types of deserts can also be cold, like the Gobi Desert. A scorching hot desert like the Namib Desert in Africa cools rapidly each night when the sun goes down.

Which of the following is a behavioral adaptation that many animals living in a hot desert have developed to help them survive in a desert biome climate?

a
nocturnal, active only at night
b
migrating south during the winter season
c
hibernation
d
thick fur coats
Question 4 (6 points)
Select ALL of the following physical adaptations that plants found in a desert biome have developed to survive in this type of biome?

(Think about what we've learned about the characteristics of a desert biome climate)

a
large, broad leaves where water is evaporated quickly into the air
b
thick, waxy skin to hold in water
c
no leaves or have spines to prevent water loss
d
a shallow root system to soak up water quickly before it's evaporated
Question 5 (3 points)
Which of the following adaptations would best help a plant living in the understory or forest floor of a Tropical Rainforest biome?

a
Thin stems that bend but do not break in windy conditions
b
Small leave to reduce the amount of water loss
c
Large, broad leaves to consume as much sunlight as possible
Question 6 (3 points)
Poison dart frogs found in a Tropical Rainforest biome are brightly colored to aid in their survival in this type of biome.

Why is being brightly colored a beneficial adaptation for poison dart frogs?

a
to visually warn predators they are poisonous
b
to blend in with colorful flowers
c
to attract a mate
Question 7 (3 points)
How do extra layers of fat help animals survive in the Tundra biome?

a
It helps them sink deeper when dividing in the water to find food
b
It insulates their body to keep them warm
c
It provides them water
Question 8 (3 points)
Permafrost, the permanently frozen layer of subsoil of a Tundra, prevents plants found in this biome from pentrating this solid layer in order to grow deep roots.

What is a special adaptation that Tundra biome plants have developed to overcome this in order to survive there?

a
growing in clusters since clumping helps protect them the cold and wind
b
growing very tall to help reach more sunlight
c
large, broad leaves to help them get rid of excess water
